“…Residual stresses are an inevitable byproduct of materials processing and treatment [1]. Various mechanical manufacturing processes, such as casting, machining, welding, heat treatment, and assembly, all generate residual stresses in workpieces to varying degrees [2][3][4][5]. Residual stress is considered to be a crucial technical factor that must be considered when it comes to affecting the high-quality development of the manufacturing industry.…”

Incremental hole drilling is a commonly employed semi-destructive method for measuring internal residual stresses. It involves calculating internal residual stresses through the measurement of strains. The conversion of strain to stress is achieved through calibration coefficients, the accuracy of which directly influences the precision of residual stress measurements. These calibration coefficients are predominantly determined through finite element simulations, which must consider the sample’s characteristics and realistic experimental conditions. While there has been extensive research on the influence of sample thickness, the impact of thickness under different experimental conditions remains unexplored, and the underlying physical mechanisms driving thickness effects remain ambiguous. This paper addresses this gap by employing finite element simulations to investigate the impact of thickness on calibration coefficients under three commonly utilized experimental conditions. Moreover, this research endeavors to elucidate the physical mechanisms that contribute to variations in these coefficients through energy analysis.

“…However, the majority of authors, e.g., [ 39 , 40 , 41 , 42 , 43 , 44 , 45 ], studied this phenomenon as only welding problems or metal forming problems, thus separately and not as two consecutive steps. Some authors [ 46 , 47 , 48 ] dealt with the determination of residual stress in formed members and predicted results were compared with the experiments (sectioning, hole drilling method and X-ray diffraction). On the other hand, Lee et al [ 49 ] identified manufacturing variables (and the determination of residual stresses was one of them) that are closely related to the surface defects in the exterior panels of large commercial vehicles.…”

Experimental and Numerical Analysis of the Residual Stresses in Seamed Pipe in Dependence on Welding and Metal Forming

Concerning the increasingly widespread utilization of the finite element method (FEM), the concept of the so-called virtual factory is also gaining ground, and not only in the engineering industry. This approach does not use numerical simulations of individual production technologies separately but treats the entire production process as a chain of interrelated technologies. Thus, the output data from one technology is taken as input data for the following technology. The resulting thermal and mechanical effects are then not only dealt with within one technology but always comprehensively within the production process. In the consideration of the loading and subsequent service lives of manufactured components, values of residual stresses are one of the very important characteristics. For these reasons, this paper deals with the effect of residual stresses’ magnitude and distribution during the formation and the final springback of the seamed pipe end section with and without respect to the influence of the preceding welding. The resulting residual stress values from numerical simulations are subsequently compared with the actual values of residual stresses experimentally measured using X-ray diffraction.

“…Additionally, Yu et al gave an extensive literature evaluation for studies that discussed cold-formed and hot-rolled steel data after being subjected to fire [ 12 ]. The review by Diaz et al covered methods used in previous studies—both computationally and experimentally—to assess residual stresses in CFS members [ 13 ]. More recently, Liang et al reviewed the prior studies on the CFS structures’ thermal performance and the optimization of CFS structural sections [ 14 ].…”
